Nov 14, 2012 9:00am PST annenberg media ♪ when we look at a sunset, we see waves of light energy that have traveled an immense distance to reach our eyes. when we look at an ocean, we see waves of water energy that may have journeyed thousands of kilometers to reach our shores. most waves derive their energy from the wind. as the wind blows over the ocean, some of its energy is transferred to the surface, forming waves that move through the water. and it is in large part the power of these waves that makes the coastal environment such a dynamic place. coastal areas are among the most beautiful and desirable places anywhere on earth. the coast and coastal land forms like this beach are the result of a dynamic interaction between two competing geologic agents-- the rocky land masses and the energy of the ocean. people tend to think of these as separate and independent from one another, but by ignoring the intimate connection between land and sea, they fail to realize that this delicately balanced system is subject to continual change. building walls and boardwalks and homes on a shifting coastline is a gamble w

me but basic terminology that we see drawn out of the tradition of chi- material energy, li- the principle of spiritual energy and together the two combined to be the essence of everything that exists. so, inside me, inside the table, inside everything that's in this room, that's going on, that kind of balance here. mythic; two names it's a vast panorama of scholars, and princes, and kings, and dynasties as you may well know but the two key names that come up in the mythic dimension; in other words the great leaders, if we must have leaders. confucius of course; the great scholar, drawn from his name becomes confucianism and lao tzu the mysterious. some say he didn't even exist; we're not sure when he existed but the composite leader-- and we will have an expert thank goodness on here because i am certainly not one. dr glenn shive will be with us to help us sort through some questions. but i couldn't help but think when we look at the yin yang symbol, i'm sure this is an original insight in terms of chinese religion, but confucius is very much like a yang side with lao tzu a

that calculate the energy flow through our ecosystem from plants, say, to herbivores to carnivores. it's important to understand the effects of species on one another because that is changing quite a bit these days. many species are going extinct due to human activity, and also new species are invading ecosystems due to human activity. ecosystems form much more tightly connected networks than many other networks. what happens is that each species is typically within three links of all other species within the ecosystem. that's a lot closer than, say, the six degrees of separation that is supposed to separate human's familiarity networks, "who knows who" within, say, the u.s. and so these are tight networks where effects on one species can propagate to many other species quite quickly. one of the most famous examples of the effects of one species on the others within the ecosystem through the network that we've been studying is the sea otter example. back in the 1800s, the russians and several other western countries paid native americans to hunt sea otters pretty much to the extinction

the same way and some of the same tactics apply and it's very high-energy. this is a very sophisticated, broad-based, well-funded attempt to essentially overturn the secretary of defense's decision to kill the crusader program. poussaint: meanwhile, united defense's paid lobbyists were on the job on capitol hill, targeting members whose constituents had a stake in the fight. and lobbyists can be expensive. for hundreds of thousands or millions of dollars, you can either get a government contract for billions of dollars or get a tax break that may be worth hundreds or millions or billions of dollars -- i mean, it's a relatively small investment. poussaint: but if it seems that companies like united defense have all the clout, it would be a mistake to underestimate the power of an incumbent president. they carry a pretty doggone big stick. as a matter of fact, they don't carry sticks, they carry clubs. 95% of what's in this enormous defense budget never gets discussed publicly at all. and so you need events like this to sort of show there are people watching, there are people for things,
